Most maintenance required by Kingkraft products is simply a visual inspection to check that the unit is
in safe working order. A check-list for these items may be found below.
If you find any faults with the unit, ensure they are rectified immediately and in any event before the
bath is next used. If in doubt about any repair procedure, please contact Kingkraft for advice or to
arrange a service visit.
The Easibath tub and panels are constructed from white polypropylene and also uses a fire retardant
GRP / gel coat as a baseboard. All cushioning PVC outer material and filler foam is also fire retardant.
No naked flames are to be in the vicinity of the bath.
Thermal mixer valves (TMVs) if fitted require special maintenance and testing to ensure they are safe
and continue to operate effectively. These requirements are set down in the Department of Health
guidance document
‘Safe’ hot water and surface temperatures
, published by HMSO, ISBN 0-11-
322158-4. Under special circumstances, for example in a domestic dwelling, if specified by the user,
the thermostatic mixing valves used by Kingkraft may not be tested to the DO8 standard or may be
omitted.
The maintenance procedure for TMV’s is as follows. This procedure should be carried out at least
annually for baths in domestic premises, and more frequently where the bath is used by more than
one person or in hard water areas.
1. Check the temperatures of the inlet and outlet for the TMV as follows:
1.1
Record the temperature of the hot and cold water (inlet) supplies;
1.2
Turn the bath fill control, to fill the bath, so the water flow is at maximum and record the
temperature of the water flowing into the bath.
1.3
Set the bath fill control so that the flow of water into the bath is at a minimum and that the
water temperature as it flows into the bath is as high as possible. Record the temperature of
the water flowing into the bath. (N. B. do not set the flow of water so slow as to allow it time to
cool down before it reaches the measuring apparatus).
1.4
While measuring the temperature of the water flowing into the bath, turn off the cold water
supply to the mixer valve and record the maximum temperature reached.
1.5
Continue to monitor the temperature of water flowing into the bath after the cold water supply
to the TMV has been switched off and record the final temperature reached.
1.6
Compare the temperatures measured with those recorded during the last maintenance
checks on the mixer valve / tap (or with the initial commissioning temperatures which are
recorded in the documentation accompanying your new bath)
1.7
If any of the temperatures has altered by more than 1°C, or if the maximum temperature
recorded exceeds 43°C, the TMV requires maintenance as in section 2 below.
1.8
Retain the records of temperature measured for future reference (a sample record sheet is
provided below.)
2.
Checks on the TMV
2.1
Check all in-line and integral strainers are clean.
2.2
Check all in-line and integral check-valves and anti-back siphonage devices are in good
working order.
2.3
Check all isolating valves are fully open.
2.4
Repeat stages 1.1 to 1.6. If the temperatures measured have not stabilised within a degree or
two of those recorded on the last maintenance check, the valve / tap must be removed for
specialist servicing. Contact Kingkraft for further advice.
